FRUlT-JAR-GOVER FASTENING.

S PECIPICATION forming part of Letters Patent No. 296,701, dated April8, 1884. Application filed March 5, 1884. (No model.)

To all whom it may concern Be it known that we, PHILIP LYON and JosnrnH. Bossnnn, citizens of the United States, residing at East Stroudsburg,in the county of Monroe and State of Pennsylvania, have invented certainnew and useful Improvements in Fruit-Jar-Gover Fastenings; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains tomake and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention, and is aperspective view. Fig. 2 is a view of theunder side oft-he clamping-bar.Fig. 3 is a vertical section through the clamping-bar and a portion ofthe jar.

This invention has relation to fastenings for securing the covers offruit-preserving jars in position; and it consists in the constructionand novel arrangement of a transverse clamping-bar having a centralprojection, and a central threaded perforation. extending through saidprojection, and, engaging said perforation, a set-screw having aflattened expanded foot, formed with operating-lugs on its marginalportion, all as hereinafter set forth.

In the accompanying drawings, the letter A designates ajar having anexterior head or collar, 12, around its neck, and (J represents thecover which is to be fastened to the jar, a packing, d. of rubber, beingusually placed between the edge of the cover and the upper shoulder ofthe collar-head b.

D represents a transverse clampbar having downwardly-extending ends, EE, each of which terminates in an inwardly-turned catch end, g, which,when said clamp-bar is in position across the top of the cover, isdesigned to engage the under shoulder of the collar [2 of the jar.

On the under side of the clamp-bar, at, its middle portion, is raised aboss or projection,

71, and a threaded perforation, It, extends upward through said boss andthrough the bar,

of which it forms a part.

Engaging the perforation k is a set-screw, L, which is operated by meansof an expanded foot, m. This foot is broad and fiat, and is usuallyslightly rounded in convex form on the under side, as shown in thedrawings. It is usually made in rectangular form, and is providedwith'the operatinglu gs 2, which project outward from its margin.

WVhen the clamp is in position across the top of the cover, its catchends engaging the collar of the jar, the set-screw is readily turned bymeans of its broad foot, which is at the same time. by the action of thescrew-stein in the threaded perforation of the clamp-bar, brought tobear' precisely upon the central portion of the cover, forcing ittightly down upon the shoulder of the collar or upon the packingthereon.

Having described this invention, what we claim, and desire to secure byLetters Patent, 1s

1. A fastening for jar-covers, consisting of a transverse clamping-barhaving a central projection, and a threaded perforation extendingthrough said projection, and, engaging said perforation, a set-screwhaving a flattened expanded foot, formed with operating-lugs on itsmarginal portion, substantially as speciiied.

2. The transverse clamp-bar having downwardly extending arms formed withcatch ends, and a central threaded perforation, and, engaging saidperforation, a set-screw having a flattened convex bottom foot, formedwith marginal operating-lugs, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
